Title: Coupling multiple master busses esp. for spatially distributed systems - using bus clock edge-related transfer of coupling set=up messages
Inventor: BELTZ DIETMAR DIPL ING
IPC: G06F13/40
Filed: 1990-05-25
Abstract: A method of coupling multiple master busses involves identical coupling-decoupling modules in each bus and sync. bus protocols in the coupled state.  Coupling involves a coupling request from the primary bus, an acceptance from the secondary bus and a primary bus opening message. Messages are passed via the modules using bus clock edge related transfer.  Other coupling point messages are suppressed whilst a coupling point is being set up. USE/ADVANTAGE  - Esp. for coupling a primary bus with at least one secondary bus, e.g. in spatially distributed process control systems, to increase efficiency whilst preserving processing times.

Inventor: HAMANN CHRISTOPH DIPL PHYS
IPC: B23K26/04
Filed: 1990-09-12
Abstract: Determining the focal distance of an energy beam, esp. a laser beam, during surface working of a workpiece, consists of measuring the intensity (A) of surface light over a time period (T) during the working of a workpiece with specific distances (D) between focussing device and workpiece.
